Plastic building blocks are good for building molecules because of some useful properties which they possess. For instance, plastic are flexible, they can be easily manipulated and can be made into any shape, size and combination. They can also be produced using different colors. Because of these features, they can be used to build and to explain how molecules behave.

Predict the reactants of this chemical reaction. That is, fill in the left side of the chemical equation.

Troyanec [42]

Answer: $Ca(OH)_2+2HCl\rightarrow CaCl_2+2H_2O$

Explanation:

Neutralization is a chemical reaction where an acid reacts with a base to form salt and water.

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side.

The balanced chemical equation will be:

$Ca(OH)_2+2HCl\rightarrow CaCl_2+2H_2O$

Thus the reactants are calcium hydroxide $(Ca(OH)_2$ and hydrochloric acid $(HCl)$

Draw the organic and inorganic products for the following acid/base reaction as well as the charges.

Reptile [31]

<span>The product would be :
H3O+ Benzaldehyde -----> C6H5CHO.
It will form a neutral molecule. So the charge is neutral.
I hope it helped.</span>
